Compact, lightweight laser sight outputs a bright green pulsating beam that’s more visible to the human eye in all lighting conditions and over longer ranges. Mounts in seconds on any pistol, rifle, or shotgun with 1¾" or more of Picatinny or Weaver-style rail space. Ambidextrous switch is comfortably positioned for quick engagement when pistol shooter’s index finger rests along the slide in the Universal Cover Mode. Low-profile housing allows many guns fitted with the Uni-Max to be carried in standard holsters. Integral Picatinny rail on underside of housing allows mounting of tactical weapon light. Windage and elevation adjust easily with the included tools, also used to set beam output mode. Normal battery life is 1 hour. Timeout circuit automatically turns the unit off after 10 minutes to extend battery life. Operates in temperatures from 40 to 100° F.
